Airflow monitor modules (AFM) and airflow monitor kits provide an economical solution for indicating fan or blower airflow. The AFM module has a contact closure that activates when airflow falls below 8.2 ft/s due to fan filter clogs or foreign materials coming in contact with the fan blade. They are field retrofittable and mount via a clip or a clamp to a protective plastic grill or guard.
The AFM Kit includes the AFM module, mounting clip, plastic guards, alarms, and power supply.
